This invention described herein maybe manufactured and used by or for the Government for governmental purposes,'without the payment to me of any royalty thereon. 1 his invention relates to a-clampingtool for use in splicing ropes or cables and particularly to toolsof this character adapted for use to retain the bight of a rope or cable around a thimble while the cable is, being spliced.

One object of my invention is to provide a splicing clamp tool with means for readily securing the bight of a rope or cable around a thimble.

Another object of my vide a splicing clamp tool which is adapted to receive and hold any size thimble sur- -rounded by the bight of any size rope or cable. Another object of my invention is to provide a splicing clamp tool, having its major piece which permits the tool to be easily an cheaply manufactured and at the same time rovides one'of .durable and. an; rugged constructmn.

till another ob'ect of m invention is to provide a splicing clamp too adapted to hold a rope or cable firmly pressed in at the point portion lies snugly against the point.

. The usual t e of splicing clamp ools now employed or'holdmg a rope or table about a thimble are madein numerous sec tions thus making the tools expensive to construct, diflicult to secure to a rope or cable, and areiattached to the cable in such a mani ner as'to re uire the use of pliers or wrenches,

thereby ma ng the operation thereof clumsy It-is therefore the aim andpurpose of this invention to devise a splicing clamp .tool -.,which is simple and cheap t'o'construct, eflicient in use, readily applied to and removed from a cable to which it ma be attached and is not liable to get out of 0 er. I

With the above and other objects and ad-' vantages in view the. invention preferably ctfmsists in the arrangement and combination .0

invention is to proaccompanying drawing; it being understood however,'that various changes inform and proportion and other details of construction may be resorted to without departing'from the spirit .or sacrificing any of the advantages of this invention.

Referring more particularly 'now to the accompanying drawin in which correspond ing parts areindicate by similar reference characters,

Fig. 1 is a perspective view of one form of my invention showing-how my clamp engages the cable or rope for splicing;

Fig. 2 is a longitudinal sectional ,view taken on line 22 of Fig. 1 with the cable and its adjuncts removed; 4

Fig. 3 is a cross sectionalview taken on line 3 -3 of .Fig. 1, and

r Fig. 4 is a perspective view of a modified form of my invention. I

In the illustratedembodiment characterizing this invention,- the yoke shaped memher 1 is made of a single casting of' metal or of the yoke shaped member 1 is vVshaped of a thimble so that the throat of the spliced the yoke shaped member 1 are series of The surfaces 9 of the ends 8 divergeinwardbeingformed by the extensions 6 and '(of the.

ends 8 of the side walls 2 and 3.

Formed in the surfaces 9 of the ends 8 of grooves 10 and 1 1, which series of grooves 10 j and 11 converge from dimensions corresponding to a maximum size thimble surrounded by the bight of a cable down to dimensions of a minimum size thimble surrounded by the bight of a cable; where they are joined by the cross iece 12 for connecting the ends 8 of the yo e shaped member 1.- together.

ly as shown at 13 and 14 to accommodate the bight 15 of a rope or cable 16 surrounding the thimble 1 7.

The rear wall .4 of the yoke shaped member 1 is provided with a screw threaded opening '18 through which a clamping screw 19 is arts to be hereinafter more fully de-. 50 scri and claimed and illustratedin the screw 19 is a peripheral groove 21 and the threaded. v

Near the inner end 20 of the clamping outer end thereof is provided with a knurled handle 22 for the-purpose of normal rotation.

The inner end 20 of the clamping screw 19 enters an aperture 23 in the rear surface 24 of the follower member 25 as shown in Fig. 2 of the drawing and is attached thereto by means of a securing pin 26 which enters a vertically formed .passage way 27. The securing pin 26 engages the peripheral groove 21 on the inner end 20 of the clamping screw 19 to lock the screw 19 against longitudinal motion relative to the follower member 25 and to rotatably engage said screw 19.

The face 28 of the follower member 25 adjacent the open end 5 ofthe yoke shaped member 1 comprises a series of superimposed grooves 29 registering with the above mentioned grooves 10 and 11 in the open end 5 of the yoke shaped member 1 and are interrupted by a recess 30 to receive the eye 31 of a turnbuckle 32 attached to the rope or cable thimble 17. i

The side 3 of the follower member 23 is provided with a longitudinally. extending groove 33 to slidably engage a locking and guiding member fixed in said yoke shaped the rear end4 of the yoke shaped member 1. The bottom of the yoke shaped member 1 is closed by the floor member 39 which contains a longitudinally extending aperture 40 to receive the free end of a turnbuckle not shown. The knurled handle 22' is provided with the hand grip 41 tomanipulate with a better purchase the follower member against the bight of a rope or cable not shown. 1

In operating my clamping tool, the rope or cable 16 to be spliced is placed around a .thimble 17 and positioned within the pair of grooves 10 and 11 of the V shaped opening 5 of the yoke shaped member 1 which corresponds in size to the dimensions of a thimble surrounded by the ibight of the cable to be spliced. The point 42 of the thimble 17 proje'cts outwardly of the yoke shaped meme ber 1. The knurled" handle 22 is now operated causing the clamping screw 20 to move the follower member 25 in a forward direction until one of the grooves 29 on the face 28 of the follower member '25 engages j the rear portion of the bight'15 of the cable 16.

' This operationwillmake it possible to se cure a tight splicing and a proper throat seizing at the point 42 of the? thimble .17

the cumbersome method of splicing cables is 1 eliminated and an expeditious tool is provided for holding the bight of any size rope or cable surrounding. any sizethimble.

Now that I have disclosed my invention what I claim as new and useful is:

1. A splicing clamp tool adapted to retain the bight of a rope or cable around a thimble to be secured therein upon splicing, comprising a yoke shaped member and a follower member therein, and means for operating said follower member, the open end of said yoke shaped member and the side of said follower member adjacent thereto having a series of grooves, each groove complementary to the shape of a thimble.

2.

3. A splicing clamp tool adapted to retain the bight of a rope or cable around a thimble to be securedtherein upon splicing, comprising a yoke shaped member provided with a bottom, an elongated aperture in said bottom to receive one end of a turnbuckle linked with the bight of the rope or cable .on said thimble, a follower member seated on said bottom within said yoke shaped member, and means for operating said follower member toward the open end of said yoke shaped member, the open end of said yoke shaped member and the side of said follower member adjacent thereto having a series of shape of a thimble surrounded by the bight of a rope or cable.

4. A splic ngclamp tooladapted to retainthebight of a rope or cable around a thimble to be secured therein upon 'splicing, compris-i or cable.

5 5.
